, 1947, Serial No. 771,229 (Cl. 30--125) Application August 29 3 Claims.

The present invention relates to structural and functional improvements in a, so-called sportsmans knife, that is, a hunting knife characterized by a special handle construction.

More specifically, novelty is predicated upon provision on a huntsmans knife of a transparent hollow handle with a suitable closing cap for the outer end thereof, said handle providing a receptacle which lends itself adaptably for convenient storage of miscellaneous items such as matches, fishing hooks, string, first aid articles, etc.

Manifestly, I am sufficiently conversant with the prior state of the art to appreciate that the adoption and use of a recess in a handle and the closing of the recess with a cap or the like whereby to provide storage space for articles, is not new. As a matter of fact the broad idea just touched upon is covered, for example in a patent granted to F. L. Putney 912,411 granted February 16, 1909.

My aim is to structurally and otherwise improve upon Putney and any other type handles in the same category through the use, choice, and selection of elements and parts not heretofore utilized in this specific line of endeavor.

In carrying out the principles of the invention I have evolved and produced a structural adaptation wherein the knife blade, which is more-orless conventional in form, is attached to a head, said head being adapted to accommodate one end of a glass tube, there being an annular ring spaced from the head, and a connecting member between the rin and head, whereby to thus provide an adaptable mount for the cylindrical transparent tube or grip and closing cap means therefor.

Other objects and advantages will become more readily apparent from the following description and the accompanying illustrative drawing.

In the drawing:

Figure 1 is a view in side elevation with parts broken away and shown in section illustrating the improved handle construction and showing a simple screw plug constituting the closing cap;

Figure 2 is an enlarged fragmentary view showing the details of the principal parts which go to make up the completed handle construction;

Figure 3 is a perspective view of the adaptor means and blade carried thereby; and,

Figure l is a perspective view of the transparent cylinder forming the principal part of the hand grip.

Reference being had to Figure 3, which the skeleton construction,

shows it will be seen the that 55 by the marginal rim of flange cap or plug this comprises a suitable blade 5 attached at its inner end to a disc-like head 1, said head: having a reduced circular portion 8 defining a. ledge 9 and a keeper to accommodate the end portion of the glass, plastic or transparent cylinder ill. The afore-mentioned ring or annulus is denoted by the numeral H and this is provided internally with a keeper channel or groove l'2'. The annulus is connected eccentrically to the keeper 8- by way' of a rectilinearly straight rod t3. The parts so far described form the afore-mentioned skeleton frame Work M which includes, as a part, the blade 6.

Considering Figure 2 it will be seen that the end portion of the glass cylinder fits over and surrounds the annulus H and is held inplace 55 of the closing H3.- The latter includes a cylindrical plug portion H which telescopes into the annulus and which is provided at diametrically opposite points with pivotally mounted latches IS. The outer ends of the latches project through apertures provided therefor and are latched in the keeper groove 12. The cap and plug have a central bore providing a passage ill for a suitable finger operated plunger 20. The plunger is hollow and cylindrical and provided with a return spring 2! which is anchored in place on a suitable attaching pin 22 as shown in Figure 2. The plunger has diametrically opposite recesses and the adjacent inner ends of the latches fit into the recesses. Hence, by pressing in the plunger against the tension of the spring means the latches are tripped and disengaged from the keeper groove !2. This makes it possible to readily remove the cap. In placing the cap in position it is simply forced in and the latch is automatically snapped into place and. holds the cap set.

If instead of using the latch equipped cap a simpler arrangement is preferred it is possible to provide the annulus Ha (see Figure 1) with internal screw threads to accommodate the screw plug 23 carried by the closing cap 24. It is obvious that by slipping the glass tube or cylinder over the ring H, rod is and seating the inner end against the ledge 9 and placing the inner edge portion around the disc-like keeper 8, after the cap is fitted into the annulus, the glass cylinder is thus held in assembled position. If desired, the glass cylinder may be fixed to the head i in any suitable manner whereby to obviate the necessity of holding same in place with the flange portion of the closing cap.

As previously stated the knife was primarily designed for use by sportsmen and it features a hollow transparent handle with a quickly removhereinafter claimed.

Minor changes in shape, size, materials and rearrangement of parts may be resorted to in actual the invention as claimed.

. Having described the invention, what is claimed as new is:

of said cylinder.

2. In a structure of the class described, a circular head, a blade attached to and projecting from said head, an annulus spaced from said head, a connecting rod between said annulus and head, an open-ended transparent cylinder form ing a hand grip,

said cylinder fitting over said and a blade mounted on the opposite side of said head.
